Letters Patent No. 87,469, dated March 2,1869.

W IMPROVEMENT IN SHUTTER-I'ASTENER.

'fha Schedule referredto in these Letters Patent and making part of thesame.

close the blind, so that, if the pressure is now removed from theprojection F, the but A will not again enter the notch f, but willremain unfastened, and the blind can then be readily and easily closedwith the same hand which caused the pressure.

Various modifications of my invention can be made, without departingfrom the invention, viz, any of the parts can be made longer, shorter,wider, or thicker, in proportion to the rest, than as shown in thedrawing, should it, from the condition of the substance use d, be foundbest to do so. A

The part E, in place of being bent downward, can

be left in astraight line with the spring D, and the projecting portionof it, E, (see iig. 1,) turned up, and fastened to the rear face of thewing A' of the but.

The standard G can be made longer, if more, or shorter, if less actionis required.

The device may also be used as it is, or in a modified form, for thepurpose of fastening the blind shut, when closed, by attaching it inanother manner to the blind,or some part of the'house 4or window-frame.

Many advantages are gained by my invention, among which are thefollowing: Y

lt enables a person to close the blind, or shutter, by the use of onehand, (or one finger, even,) leaving the other hand free to hold up thesash, or to hold fast to the window-stool, to prevent falling ont of thewindow.

Or, if the sash'is held up by weights or otherwise, it enables a personto close both blinds at once, by using both hands.

It can be readily used in connection with nearlyally forms and kinds ofblind-buts now in use.

To the buts of blinds alreadyhung, it can be applied without removingthe buts from-the `blind or house, thereby saving much 'labor anddefacement.

v it requires no peculiar form of but to be made for it.

1t enables a person to remove the blind at any. time,

even when fastened open. l l

ltprevents the blind from striking tbe outside of the house, and, bysuch striking, .marring the blind and the house, and causing adisagreeable noise, coming in contact with the but only to a verylimited extent.

-When painted, its action is .not retarded by the paint, as in nearlyall blind-fasteners.

Being made of flexible met-al, it is very durable, and, being held inplace bythe force of the spring,conforms itself to the shape of thebottom of the but, and works well and closely, even when somewhat worn.

1f damaged or broken, a new one can be purchased, at tritling expense,and proper repairs made, Without buying a new set of buts, but, bysimply attaching a new fastener, and without removing the but at all.

' It is simply one light piece of metal, and can be cheaply made. .y

As it is light and compact, and requires no peculiar forinof but to gowith it, it can be easilyand cheaply tiiansported.- Y

It fastens itself, when the blind is pushed open, and

To all 'whom 'it may concern:

Be it known that I, Enwin S. OoLLAMnn, of the city of Georgetown,District of Columbia, have invented a new and useful Improvement'inWindow-Blind and Shutter-Fasteners; and I do hereby declare that thefollowing is a full, clear, and-exact description thereof, which willenzdole others skilled in the art to make and use the same, referencebeing had to the accompanying drawing, forming part of thisspecification; My invention has for its principal object, the partialclosing of a blind, or shutter, by pressing upon a springcatch,whichcatch also performs the function oi holding the blind open. rihis andother useful results I accomplish and secure by my present4 invention,by a simple device, which can be easily operated, reference being had tothe accompanying plate of drawings, in which- .Figure l is a top view ofthe fastener, as it is cut from 'sheet-metal, before it is bent, thedotted lines showing the points at which it is to be bent.

Figure 2' is an end view of the fastener, afterbeing bent. Figure 3 isan edge or side view of the same. Figure liis a front view of thefastener, as attached,

Figure 5 is a-rear view of the fastener, as attached, the blind beingclosed.

Figure G is an end view of the fastener, showing the position of thelfastener, and also of that portion of the but which is used on theblind, as when fastened open. i

- A and A', inthe drawing,.representl .the wings of a common but, whichmay be madeof brass, cast-iron, or'any other suitable substance.

B represents a portion of the window-frame.

O represents the blind.

D represents the spring.

E is that portion of my device which can be attached to the window-frameimmediately below the but, or to the but itself. A

. F represents a projection, upon which pressure is applied, for thepurpose of uncatehing the spring, and liberating the blind, and whichpressure also partially closes' the blind.

represents a notch in the'fastener, which catches the lower part ofthewing'A f the but.

G is a projecting strip or standard,which, as seen inI fig. 6, extendsupward behind the but, and, when the spring ispressed at F, strikesagainst the back face of -the wing A of the but, partially' closing theblind.

g represents the extreme end of the standard G.

The oper tion is as follows:

In fig. 6, theblind being 'fastened open, then, by pressing downward andbackward upon the projection F, (with but one hand,) the spring D isthrown downward, releasing the wing Al ofthe but from the notch i f,and, at the same time and by the same motion, the 'point g of thestandard G is caused to press against the rear face of wingl A of thebut, and thus partially the blind is unfhstened, and partially closed,by one The springr D, having the standard G, thumb-piece motion of thel1and, wl1icl1 motion is downward, and F, and notch j; constructed asdescribed and shown, very convenient, and but half an inch in extent.and arranged 'with the but, as and for the purpose de-I As the straincomes upon it edgewise,i1; will bear a scribed. great amount of pressurebefore breaking.

am aware that springs fora similar purpose are-'in' Witnesses: use, andam aware of the patent of Jacob Frick; but H. GARRETT,
